It was decided to extract the beast from Gaara's body. Once the plan was launched, his jinturiki status would lose all meaning. The boy's death didn't matter, as long as nothing happened to Shukaku!
Rasa considered himself a genius: he had found a way to extract Shukaku while preserving the beast itself. After all, if they had listened to those fools and used Gaara as a source of energy for the puppet, his accidental death would have created huge problems.
What? Will Gaara die while extracting the Caudate?
Well, let it be. If he dies, he'll die. In any case, the race didn't care about this son, a simple weapon, a tool. And now that there's a better tool, what's the use of the old one?
— Now everything is ready. All that remains is to improve this super puppet!
Rasa looked at the slowly pulsating energy source that looked like a huge heart, and a satisfied smile appeared on his face. He had already imagined how, controlling this invincible puppet, he would crush Uchiha Yue.
Still, it wasn't enough.
According to calculations, this puppet should have incredible durability, the ability to regenerate, and an almost endless source of energy, as well as the ability to fire Bombs of the Tailed Beast. Moreover, her strength was based on the senjutsu chakra, which made her even more powerful.
In fact, after the completion of the project, this creation would have become virtually invincible in the world of Shinobi. No one could have destroyed it.
This meant that even if they couldn't get their hands on Uchiha Yue's Mangekyo Xiaringan, they would still be able to forcefully suppress the entire world with this puppet.
The only drawback of the machine was the lack of the crushing power of Uchiha Yue's eyes. After all, his eyes could destroy an entire country with just their appearance. The ultimate weapon is compact and portable. As long as it belonged to the owner, it was impossible to take it away without killing the wearer.
But you could try to capture the super puppet.
However, upon realizing this, Rasa calmed down. For the sake of Uchiha Yue's eyes, they would not dare to act with full force, so as not to damage the priceless dojutsu. But if you didn't attack to the limit, Uchiha Yue could find a chance and activate Izanagi. According to their assumptions, if you drag out the fight, then even after using this technique, the weakened eye will eventually recover.
It was like a nefarious boss in a game that regains health if you don't defeat it in the allotted time.
But now everything has changed. Rasa suddenly realized that getting Uchiha Yue's eyes was the ideal outcome, but even if they were accidentally destroyed, it would not prevent the Village of Sand from rising to the top of the world after the war and parasitizing others. He made a firm decision.
When the time comes, he will unleash all his might on Uchiha Yue so that he does not even have time to think about Izanagi. Destroy him once and for all!
Those eyes... If they don't get them, then no one will.
But is the so-called "endless energy" of the Tailed Beasts really true?.. endless?
In the distance, one of the researchers raised his head and rubbed his eyes. Looking at the heart-like energy source sealing Shukaku, he suddenly wondered this question.
"Hmm..."
A thought shot through his mind like lightning. The pupils narrowed. It was akin to how Newton first wondered why an apple falls from a tree. Everyone took it for granted, but... Why?
Why is the apple flying down instead of into the sky?
Why should something that has always been like this remain like this? There must be a reason!
Why do Tailed Beasts have so-called endless energy? It's against the laws of nature!
Soon, his thought infected other scientists as well. Everyone started asking the same question: why? They began a really thorough investigation of Shukaku. Previously, they would hardly have been able to detect anything, but the data on senjutsu obtained from Mount Meboku changed everything. Soon they noticed that the fluctuations of natural energy around the beast were unusual, and they made a bold assumption: perhaps the Tailed Beasts were able to convert natural energy into chakra.
This is the secret of their "infinite energy." She doesn't appear out of nowhere!
Realizing this, the researchers broke out in a cold sweat. Their plan will have to be changed.
— What, send Shukaku to the Area of Dead Silence for an experiment? Rasa frowned, looking at the scientist standing in front of him.
Shukaku's existence was incredibly important to Sand Village right now. If something happened to the beast, their plan would fail. Send him outside... It's too risky.
He was about to refuse, but the researcher managed to state their assumption. Rasa looked at Gaara's lifeless body.
Soon, under his personal escort, they brought the energy core to the border of the Dead Silence Region and placed it inside.
The experiment proved them right. The so-called endless chakra was the result of the mysterious connection of the Tailed Beasts with the natural energy of the Shinobi world, which they continuously absorbed and transformed into their own.
Shukaku was extracted from Gaara out of fear that the boy might accidentally die along with the beast if used as an energy source. But now that Shukaku had lost that status, a new plan was needed.
In other words...
Gaara died in vain.
If they had guessed this before extracting the beast... However, Gaara's fate would most likely have been the same. As already mentioned, Shukaku was too important to the village. What if something had happened to Gaara himself during transportation? The risk was unacceptable.
